I saw this for the first time on eBay. Anyone who has one or used to have one care to share their experience with it? How height adjustable is it? I'll hang up and listen.

If you ask Google, it takes you to their site.
Looks like they have different models, with different heights.
Filled with Tidy Cat, cat liter.
No freak'n wonder it's hard to find liter now!!
